Self-sweeping laser twist bit

The invention provides a self-sweeping laser twist bit, and relates to the technical field of lunar resource exploration drilling tools. The twist bit solves the technical problems that the cutting efficiency of a drill bit is general and rock debris is difficult to discharge. The self-sweeping laser twist bit comprises a twist bit body, a self-sweeping device, a mixing device, a laser assembly and a light transmitting assembly; the laser assembly is arranged in the mixing device; the mixing device is arranged in the twist bit body and is used for grouping and guiding laser beams emitted by the laser assembly; the light transmitting assembly is arranged on a light transmitting hole of the twist bit body and is used for transmitting laser; the self-sweeping device is connected with the light transmitting assembly for sweeping the light transmitting assembly; and the self-sweeping device is a self-sweeping device without external power input. The twist bit is used for lunar geological drilling, has the characte
